Question

If 15% of 40 is greater than 25% of a number by 2 , find the number.​

Answer 1

Answer:

the number is 16

Step-by-step explanation:

Let the number be x

15% of 40 - 2 = 25% of x

or, (15x40)/100 - 2 = 25% of x

or, 600/100 - 2 = 25% of x

or, 6 - 2 = 25% of x

or, 4 = 25x/100

or, 4=x/4

or, x = 4x4

.: x=16

Answer 2

Answer:

16

Step-by-step explanation:

let "a" be number then

15% × 40=25%×a +2

=>6= 25%×a +2

=>6-2/25% =a

=>4/(1/4) = a (because 25%=25/100)

hence a = 4/0.25 = 16
